Power Tool Device

Abstract

A power tool device, in particular a portable power tool, includes at least one signal switching unit that has at least one signal switching element that is actuable at least in order to activate a drive unit of the power tool. The power tool device further includes at least one operating mode selection unit that has at least one operating mode selection element that is actuable in order to select an operating mode of the drive unit, and at least one locking unit that has at least one locking actuating element at least for locking the signal switching element. The power tool device also includes at least one electronic unit that is configured to control and/or regulate the drive unit at least depending on an evaluation of a setting parameter of the locking actuating element.

1 . A power-tool device, comprising:
 a drive unit;   at least one signal switching unit including at least one signal switching element configured to be actuated at least to activate the drive unit;   at least one operating-mode selection unit including at least one operating-mode selection element configured to be actuated to select an operating mode of a plurality of operating modes of the drive unity;   at least one locking unit including at least one locking actuating element configured to lock the at least one signal switching element; and   at least one electronic unit configured to control the drive unit, by open-loop and/or closed-loop control, at least in dependence on an evaluation of a position characteristic of the at least one locking actuating element.   
     
     
         2 . The power-tool device as claimed in  claim 1 , wherein the at least one locking unit further including at least one locking switching element that is operatively connected to the at least one locking actuating element and that is configured to provide the at least one electronic unit with the position characteristic of the at least one locking actuating element. 
     
     
         3 . The power-tool device as claimed in  claim 1 , wherein the at least one operating-mode selection unit further including at least one operating-mode switching element that is operatively connected to the at least one operating-mode selection element and that is configured to provide the at least one electronic unit with a signal relating to the selected operating mode of the drive unit. 
     
     
         4 . The power-tool device as claimed in  claim 1 , wherein the at least one signal switching unit, for providing the position characteristic of the at least one signal switching element, is configured to switch electrical currents having amperages of less than or equal to 500 mA. 
     
     
         5 . The power-tool device as claimed in  claim 1 , wherein the at least one locking unit is configured to lock the at least one signal switching element in an unactuated state of the at least one signal switching element. 
     
     
         6 . The power-tool device as claimed in  claim 1 , wherein only the at least one locking unit is configured to unlock the at least one signal switching element. 
     
     
         7 . The power-tool device as claimed in  claim 1 , wherein the at least one locking unit is configured as a bistable locking unit. 
     
     
         8 . The power-tool device as claimed in  claim 1 , wherein the at least one locking unit is configured to maintain locking of the at least one signal switching element irrespective of the operating mode of the drive unit. 
     
     
         9 . The power-tool device as claimed in  claim 1 , wherein the at least one signal switching unit has at least one speed transducer unit, which is operatively connected to the at least one signal switching element and is configured to regulate a rotational speed of the drive unit. 
     
     
         10 . A power tool, comprising:
 at least one power-tool device including:
 a drive unit; 
 at least one signal switching unit including at least one signal switching element configured to be actuated at least to activate the a drive unit; 
 at least one operating-mode selection unit including at least one operating-mode selection element configured to be actuated to select an operating mode of a plurality of operating modes of the drive unit; 
 at least one locking unit including at least one locking actuating element configured to lock the at least one signal switching element and 
 at least one electronic unit configured to control the drive unit, by open-loop and/or closed-loop control, at least in dependence on an evaluation of a position characteristic of the at least one locking actuating element.
